How to Select a Serial Cable

Signaling Standards

Several standards define the signaling over the serial connectors on the router and serial
device, the serial cable, and the cable connectors. You can connect a serial device with the
following types of connectors to the router serial port:
•
EIA/TIA-232
•
EIA/TIA-449
•
EIA/TIA-530
•
EIA/TIA-530A
•
X.21
•
V.35
Check the documentation that ships with your serial device to determine the type of serial
connector on your serial device.

Connector Gender

If pins protrude from the base of a connector, the connector is male. If the connector has
holes to accept the pins, the connector is female.
A DTE device typically has a male connector, while a DCE device typically has a female
connector.
Examine the serial connector on your serial device to determine its gender.
